| description |
According to a 2017 IEA report, energy consumption in buildings accounts for approximately one-third of the total energy consumption worldwide. Additionally, lighting represents 19% of electricity consumption globally. Given these data, there is a need to implement a solution to reduce these energy consumptions. One way to achieve this is by implementing devices that can turn work areas into smart spaces. The objective of this project is to implement a smart office by monitoring and controlling the energy consumption of electrical devices through IoT technologies, achieving significant energy savings while providing comfort to the office personnel. To achieve this, various sensors were installed, including door sensors to detect their state (open or closed), presence sensors (to determine if there are people in specific areas), and actuators. Based on the signals transmitted by these installed sensors scenes were created to enable automatic control of lighting. The central controller used for this purpose was the Raspberry Pi 4, and the Node-Red tool was integrated to establish communication between IoT devices. Node-Red is a flow-based development tool for visual programming that allows the connection of hardware devices, APIs, and online services. This tool facilitated the integration of different sensors and brands, and the programming of different scenes to achieve automatic energy savings. Furthermore, communication was established with a cloud to monitor and control the implemented system remotely, using the MQTT communication protocol. MQTT is a data transmission protocol designed for machine-to-machine data transition. A message broker server receives transmissions from devices that "publish" information on specific "topics" and subsequently delivers those messages to other machines that "subscribe" to those specific "topics." The HiveMQ services were used for this purpose, enabling the connection of up to 100 devices for free. The result of the project is a system that can be controlled remotely, and due to the implemented technologies, has generated energy savings of 6.1%. This saving reduces operational costs and supports the office´s sustainability goals. Additionally, the system provides comfort for the people working in the office. It is worth mentioning that this project is scalable, meaning that as the office expands its facilities, the system can be modified to add the necessary sensors and actuators to control the expansion effectively. |

Según un informe de la IEA de 2017, el consumo de energía en los edificios es aproximadamente un tercio del consumo total de energía en el mundo. Además, la iluminación representa el 19% del consumo de electricidad en todo el mundo. Tomando como referencia estos datos, surge la necesidad de implementar una solución que permita reducir dichos consumos. Una forma de hacerlo es la implementación de dispositivos que permitan convertir las áreas de trabajo en espacios inteligentes. El objetivo de este trabajo es la implementación de una oficina inteligente, monitoreando y controlando el consumo energético de los dispositivos eléctricos mediante tecnologías IoT, logrando un ahorro energético significativo y a la vez proporcionando confort al personal que labora en dicha oficina. Para ello, se instalaron diversos sensores tales como sensores para la detección del estado de las puertas (abiertas o cerradas), sensores de presencia (para determinar si se encentran o no personas en áreas específicas) y actuadores, los cuales, con base a las señales transmitidas por los sensores instalados, se pudieron crear escenas que permiten el control de la iluminación de manera automática. La Raspberry Pi 4 se utilizó como controlador central, se integró la herramienta Node-Red para establecer la comunicación entre los dispositivos IoT. Node-Red es una herramienta de desarrollo basada en flujo para la programación visual que permite conectar dispositivos de hardware, API y servicios en línea. Esta herramienta nos facilita la integración de diferentes sensores y marcas, en donde se realizó la programación de diferentes escenas para poder generar un ahorro energético de manera automática. Asimismo, se estableció comunicación con una nube para poder monitorear y controlar de manera remota el sistema implementado mediante el protocolo de comunicación MQTT, el cual es un protocolo de transmisión de datos diseñado para la transición de datos de máquina a máquina. Un servidor, denominado “bróker” de mensajes, recibe transmisiones de dispositivos que “publican” información en “tópicos” particulares y, posteriormente, entregan esos mensajes a otras máquinas que se “suscriben” a esos “tópicos” específicos. Para lograr esto, se utilizaron los servicios de HiveMQ, los cuales permiten conectar hasta 100 dispositivos de manera gratuita. El resultado del proyecto es un sistema que puede ser controlado de manera remota que, debido a las tecnologías implementadas, ha genera un ahorro energético del 6.1%. Este ahorro reduce los costos operativos y apoya los objetivos de sostenibilidad de la oficina. Además, el sistema brinda confort para las personas que trabajan en dicha oficina. También cabe mencionar que este proyecto puede ser escalable, es decir, a medida que la oficina amplíe sus instalaciones, el sistema puede ser modificado para agregar los sensores y actuadores que se requieran para poder controlar dicha ampliación.
